Rhett & Link (the powerhouse behind Good Mythical Morning–abbreviated as GMM–an American comedy/talk/variety YouTube series ) play funny folk (Flying Conchords influenced?) to relax you into “Christmas Sweatz.” Take it easy! (And dig their facial dress-up “Christmas Face” for what to wear when you’re trying TOO hard.) (Who can stop at just two? They’ve swapped heads for tails just last year with “Christmas Booty.” That’s gotta be the end!)
